Inspect for defects before installation.
UPDATE: After contacting the seller, they took responsibility and sent a replacement wiring harness. I tested the replacement and it works correctly. Their customer service was responsive and professional, and for that alone they deserve five stars. Bought this in August for an engine swap. From the start, the vehicle didn’t work correctly. I initially believed the issue was engine-related, but after months of troubleshooting, it turned out the real problem was the wiring harness. The harness had incorrectly configured wires from the factory, which made the issue difficult to diagnose.

Solid Value, NOT A FACTORY REPLACEMENT. PAY ATTENTION.
Ordered as a replacement for a 1999 lm7 5.3 auto rwd truck. It could be made to work, but... Anyway, for the hundred bucks I am keeping it for parts or a stand alone swap later. Its set up for an F body car with the ECU in the cabin, Truck ECU is under hood with the boiling hot engine, its just how GM does things, anyway. Looks to be reasonably well made but read the fine print, it will require changes to things you might not want to deal with.

Get EV1 to Multec injector adapters for $12
Decent quality for the price. However comes with EV1 to EV6 injector adapters. If you have a truck motor or gen 3 you will need to purchase a set of EV1 to Multec adapters. It would be nice if the connectors were labeled but for the price point it wasn’t bad. Worked well you just have to not be incompetent and unresourceful like some of the other people who reviewed this product.

Time consuming but a good product
Everything lined up properly and was a bit difficult to install but is expected from a wiring harness. Just takes a bit of time!

Nothing fit
I don’t know what’s going on, but I match the year and the engine and not one plug fits
